Problem with uppercase letters :D

Hi all guy!!! I have writing this code but my var word don't count the uppercase letters!!!
HOW TO FIX????

Code:

<!DOCTYPE HTML>

<html>

    <head>

        <script type="text/javascript">

            function alphabet (letter)

            {

                var returnValueAlphabet = true;

                if (letter == "a" || letter == "b" || letter == "c" || letter == "d" || letter == "e" || letter == "f" || letter == "g" || letter == "h" || letter == "i" || letter == "j" || letter == "k" || letter == "l" || letter == "m" || letter == "n" || letter == "o" || letter == "p" ||letter == "q" || letter == "r" || letter == "s" || letter == "t" || letter == "u" || letter == "v" || letter == "w" || letter == "x" || letter == "y" || letter == "z")

                {

                    returnValueAlphabet = false;    

                }

                return returnValueAlphabet;

            }

            function start ()

            {

                var len = [];

                var count = 0;

                var phrase = 0;

                var numberWord = 0;

                var word = 0;

                var arrayPhrase = "Yesterday is history. Tomorrow is a mystery. But today is a gift. For this it is called present."; <------ *UPDATING  var arrayPhrase = ["Yesterday is history....ecc"];

                *UPDATING ---> ---> ---> ---> ---> --->    ---> ---> ---> ---> ---> --->      ---> ---> ---> ---> --->    

                for (i = 0; i < arrayPhrase.length; i++)

                {

                    if (arrayPhrase[i] == ".")

                    {

                        len[count] = numberWord;

                        numberWord = 0;

                        count++;

                        phrase++;

                    }

                    if (!alphabet (arrayPhrase[i]))

                    {

                        numberWord++;

                        word++;

                    }

                }

                alert ("Total words =" + " " + word + "\n\n" + "Total phrase =" + " " + phrase + "\n\n" + "Words in the phrase =" + " " + len.join (", "));

            }

        </script>

    </head>

    <body>

        <button type="button" onclick="start ()">TRY ME</button>

    </body>

</html>

*UPDATING, I reread my problem and call that the stringh "Yesterday...... ecc" is insert into a array!!!! And now all programs don t work....

Try using .toLowerCase()

Try RECODING the entire function to be more sensible.

Code:

    function alphabet (letter)

    {

        return ( letter >= 'a' && letter <= 'z') || ( letter >= 'A' && letter <= 'Z' );

    }

** OR **

Code:

    function alphabet( letter )

    {

        var letters = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ";

        return letter.indexOf(letter) >= 0;

    }

** OR **

Code:

    function alphabet( letter )

    {

        return ( /^[a-zA-Z]$/ ).test(letter);           

    }

** OR **

Code:

    function alphabet( letter )

    {

        return ( /^[a-z]$/i ).test(letter);           

    }

Or serveral other possible ways.

But *PLEASE* not by making 26 *SEPARATE* tests.

Of course, there is no reason at all to even need that alphabet function.

Code:

function start ()

{

    var arrayPhrase = "Yesterday is history. Tomorrow is a mystery. But today is a gift. For this it is called present.";



    var phrases = arrayPhrase.split(".");

    var wordsPerPhrase = [ ];

    var totalWords = 0;

    for ( var p = 0; p < phrases.length - 1; ++p )

    {

        var words = phrases[p].replace(/^\s+/,"").replace(/\s+$/,"").split(" ");

        wordsPerPhrase[p] = words.length;

        totalWords += words.length;

    }

    alert (  "Total words = " + totalWords + "\n\n" 

           + "Total phrases = " + phrases.length + "\n\n" 

           + "Words in each phrase = " + wordsPerPhrase.join(", ")

          );

}

start();

I don t see anyone of your method Pedant!!! xD
And your last comment!! It's a mystery for me \s+\... I don't think it's a code for beginner :D
However thanks for all example, I'll remember for the next time!!!!

Hi guy... This code don't work, my anti-bug crah when arrive at this part:
if (arrayPhrase.charAt(i) == ".")
Don't know how to works with the array!!!

Old Pedant

My code explained:

Code:

function start ()

{

    var arrayPhrase = "Yesterday is history. Tomorrow is a mystery. But today is a gift. For this it is called present.";



    // split breaks a sting into an ARRAY of strings, all broken

    // apart on the character (or regular expression) you give:

    var phrases = arrayPhrase.split(".");

    // so now we have each sentence (that used to end in a period)

    // in a separate element of the array named phrases

    

    var wordsPerPhrase = [ ];

    var totalWords = 0;



    // loop through all the phrases/sentences in the phrases array

    // notice that we do *NOT* process the last element of the array

    // because it will be the blank string after the last period

    for ( var p = 0; p < phrases.length - 1; ++p )

    {



        // this is the trickiest part, so let's break it down in pieces:

        //      phrases[p] :: get one phrase from the array

        //      .replace(/^\s+/,"") :: replace all *leading* spaces with nothing

        //      .replace(/\s+$/,"") :: replace all *trailing* spaces with nothing

        //      (in other words, trim the spaces off both ends

        //      .split(" "); :: split the phrase into words, just as we split into phrases

        var words = phrases[p].replace(/^\s+/,"").replace(/\s+$/,"").split(" ");



        // so now we have an array named words...and it has as many elements

        // as there are words in the phrase!



        // put the count of words in to proper element of the wordsPerPhrase array  

        wordsPerPhrase[p] = words.length;



        // and bump the count of the total number of words

        totalWords += words.length;

    }

    

    // and then just show the final numbers:

    // I corrected the value for Total Phrases from my prior post

    alert (  "Total words = " + totalWords + "\n\n" 

           + "Total phrases = " + (phrases.length-1) + "\n\n" 

           + "Words in each phrase = " + wordsPerPhrase.join(", ")

          );

}

arrayPhrase is not an array it is a string

to access a specific character charAt(nu) is required

I tested the script I posted with IE and FF

But in my inizial post i write arrayPhrase = ["Yesterday.....];
This is an array!!! I would use an array!!!

That would then be an array containing ONE element which is a string. Then arrayPhrase[0] will be the entire string and arrayPhrase[1] will be beyond the end of the array.

Using array notation to reference characters in a string has been recently introduced as an alternative to using charAt but there are still lots of browsers in use that don't support it.

So what does your code look like now. Also are there any error messages on the error console?

No error in console, but I find error!!!
When I write array = ["Yehxcwj ecc...."]
the programs read this how to one element of array, so when start cicle for (i = 0; i < array.length; i++), the programs execute only one for because the length of array is 0. How to fix this problem!?!?! Beacause my problem ask: " Is stored in an array a text of char. Print the numbers of word, phrase and word for phrase!!!".
If I use an simple var the progrma work perfectly :D

Felgall already answered that question:

Quote:

... Then arrayPhrase[0] will be the entire string ...

So just do

Code:

var text = arrayPhrase[0];

and then replace all uses of arrayPhrase after that point with text.

But I strongly suspect you are misreading the homework assignment. Or the instructor just used the wrong words. Maybe you should copy the assignment here *VERBATIM*.
